Update May 2, 2021

  1. A more secure player trade: if you play with an unauthenticated account, your trade size and frequency will be rate-limited.
  2. You can now play Rome map without Expansion Pack 1!
  3. You can now play with expansion packs on web as well: you need to own the expansion pack on Steam and sign in via your Steam account.
  4. Fix a bug where Steam backup frequency is not correct (it is now every 10 minutes).
  5. Fix a bug where trade amount has rounding error - now it has to be an integer.
